Cadmium chloride-induced lipid peroxidation in human liver carcinoma (HepG₂) cells. Cells were incubated for 48 h with increasing concentrations of cadmium chloride (1, 2, 3, 4, and 5 μg/mL). Lipid hydroperoxide levels were determined as described in Materials and Methods. * Significantly different (p < 0.05) from the control, according to the Dunnett’s test. Data are representative of three independent experiments.
